Abstract
The invention discloses a self-propelled corn combine harvester and belongs to the field of agricultural machinery. The self-propelled corn combine harvester comprises a working chassis assembly and a harvesting assembly. The working chassis assembly consists of a power system, a driving control system, a walking chassis system. The harvesting assembly is arranged on the working chassis and comprises a corn ear picking table, an ear picking table mounting rack, a primary ear elevator, a secondary ear elevator, an ear stripper, an ear throwing roller, an ear box, a stripper seed recovery device and a power transmission system which are mutually connected. The self-propelled corn combine harvester is characterized in that a straw chopper is arranged in front of a driving wheel of the walking chassis system, and is mounted under the ear picking table mounting rack in front of the driving wheel through a chopper suspension device. Due to the structure optimized design, the straw chopper is arranged in the front and is mounted in front of the driving wheel and under the ear picking table mounting rack, and the ear-picked straw directly enters the chopper to be cut. Therefore, the straw is prevented from being rolled by wheels, and the straw chopping quality is improved.
